IMPROVEMENT IN MACHINERY FOR TARRING OAKUM.

"vllerillration Iirining partei' Inllers latenl No. 22,66?, dated Januar-,Y Il", IHSAI.

To (LM whomr ifj 'n1/ay coll/cern.:

13e it known that l', licnxno AlIllNsLnv, ot' the city and county of Phihulelphia, and State of Pennsylvania, have invented a new and Ii'nproved Apparatus for Tai-ring Oaknni, and I do hereby declare the following to be a l'ull, clear, and exact description ofthe same, reference beinghad to the accompanying drawings, and tothe letters of reference marked thereon.

My invention consists in the employment for tarring oakum ol' a perforated vessel or box placed within a stationary vessel containing a mixture ol' tallow, tar, and water, or other compounds used in the manu facture ol' oakuni, a K'iet of steam being admitted to the bottom of the said stationary vessel, while a reciprocating motion is imparted to the peri'orated vessel, which contains the hemp or tow. The latter is thus thoroughly and rapidly im pregnated with the contents ot' the stationary vessel andconverted into oalium.

In order to enable others to practice my iuvention, I will now proceed to describe the manner iu which I carry it into ell'cct.

On reference tothe accompanyingdrawings, which form a part ol' this specification, Fig ure l is a sectional elevation of an apparatus for carrying out my improved mode of manufacturing oahuxn; Fig. 2, a transverse scctional elevation en the line l 2, Fig. 1.

Two vertical posts, Av and A', are erected on a foundation or tloor, li, and connected togcther at the top by a longitudinal beam, C. On the foundation is placed a vessel, D, open at the top and closed at the bottom, with the exception of a small central opening for the admission of the bent end of the steanrpipe E, which communicates with any adjacent steam-boiler, and which is furnished with a suitable stop-cock, c, for regulating the admission ol" steam to the vessel l). Another vessel, F, of the same form, but somewhat less in size than the vessel D, is suspended within the latter at the end of a rope or chain,v H, which passes through a hole in the longitudinal beam (l over the pulley I, which turns on brackets secured to the beam, and thence to a pin on the crank-Wheel J', which is caused to revolve in brackets attached to the longitudinal beam C, thus imparting a vertical reciprocating motion to the vessel F.

The latter may be made of perforated metal.

plates or ol' wire-netting, so that the compound contained in the vessell) may have free access to the contents ofthe vessel F.

K. is an ordinary crane, the stem ol` which is arranged to turn above in the beam (l and below in the foundation ll. This crane so situated that its rope or chain maybe brought to coincide with that attached to the vessel l?, when it becomes necessary to unhook one and attach the other.

The vessel l) is nearly filled with a mixture oftallow, tar, and water-the composition usually employed in the manufacture ol' oakuin. A mass o1' tow or hemp is placed in the inner vessel, F, the steam allowed to pass into the bottom ol' the outer vessel, l), and the crankwheel .I caused to turn. The contents ol the outer vessel boiled together, thoroughly amalgamated and agitated by the action ol' the jet ol' steam, pass through the perfor-ations of the inner vessel, and penetrate through its contents. Ilhe reciprocating motion imparted to the perforated vessel l and its constant ascent and descent vin the liquid contents ol' the outer vessel tend to continually change the position ofthe tow, which soon becomes thoroughly impregnated with the composition and ready for use as oakum. The rope II then nnhooked, and the rope ol the crane attached to the vessel F, so that the latter, with ils con tents, maybe hoisted u p clear of the outer vessel, and, by swinging the crane partially round, may be deposited on a perloratml platforni, in, which, with au inclined plane, n, is erected on lhe foundation Il, adjacent to and above the top ofthe vessel I). lheliquid becomes gradually drained from the tow, passes through the pertorated pla t Io rm in, au d returns to the vessel I) down the inclined plane n.

The tow, which, by the above process, has become oakum of a superior quality, after bcng partially dried, is slightly twisted, so as to assume the shape best adapted for use in calliing vessels.

The above apparatus, although applicable to the tarriug ol' oahum generally, is more especially intended for use in the hemp'lgrowing districts, where the short fibers or tow are rejected as worthless for any but the most co1n mon purposes.

I claim and desire to secure by Letters Patent- The perforated vessel F, or its equivalent,
